    Description

      I have Weblogic 12c running. My web-app is version "2.5".

      Following is a snippet from my web.xml

      <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      	xmlns="http://java.sun.com/xml/ns/javaee"
      	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
      	id="WebApp_ID" version="2.5">
      	<display-name>pec-service</display-name>
      	<context-param>
      		<param-name>log4jConfiguration</param-name>
      		<param-value>file:/C:/log4j/dev.log4j.xml</param-value>
      	</context-param>
      
      	<listener> 
      		<listener-class>org.apache.logging.log4j.core.web.Log4jServletContextListener</listener-class> 
      	</listener>	
      
      	<filter>
      		<filter-name>log4jServletFilter</filter-name>
      		<filter-class>org.apache.logging.log4j.core.web.Log4jServletFilter</filter-class> 
      	</filter>
      	<filter-mapping>
      		<filter-name>log4jServletFilter</filter-name> 
      		<url-pattern>/*</url-pattern>
      		<dispatcher>REQUEST</dispatcher>
      		<dispatcher>FORWARD</dispatcher> 
      		<dispatcher>INCLUDE</dispatcher>
      		<dispatcher>ERROR</dispatcher>
      	</filter-mapping>
      	
      </web-app>
      

      However, on my server startup I am getting the following error -

      <Aug 16, 2013 3:12:32 PM PDT> <Warning> <HTTP> <BEA-101162> <User defined listener org.apache.logging.log4j.core.web.Log4jServletContextListener failed: java.lang.IllegalStateException: Context destroyed before it was initialized..

      If I remove the listener & the filter, it works fine.


      I did some research and found that even though the web-app is version "2.5", the

      Log4jServletContainerInitializer
      is getting invoked.
